` CONCRETE-noorING-TILE MACHINE:

Application led May 9,

capable of expeditious hand operation and.

in which the tile is formed fully complete and delivered on a pallet for drying `and finishing operations. Y Y

constructive details, one being the provision of adjustable means for levelling the raised` end4 edges of the tiles uniformly, another to furnish .means for forming the corners of the tiles.interengagingly, and finally, to arrange the machine so that tiles of different conformation can be made therein.

These and other objects, which will appear as the vdescription progresses, are attained by the novel construction and combination of parts Vhereinafter described and shown in the accompanying drawings, forming a material'part of this disclosure, and in whichl Figure 1 is afperspective view showingthe upper portion of atile machine made in accordance with thed invention.. j

Figure 7 is a perspectiveview of oneform of tile as made in the machine, showing the joints between adjacent elements.

Figure 8 is an enlarged perspective view showing the removable block constituting the head of the mould.

Referring, particularly to Figure 7 of the drawings, the numeral 10 designates in general a series of rooting tiles, the same having curved longitudinal arches 11 raised from the general level 12, and along one of their lateral edges are raised ribs 13 having between'them a recess 14 adapted to engage a corresponding tenon 15, formed on the A further Objectis in `the'improvement of 192e. seiai no. 559,551.

under side of the edge of the adjacent tile, the arrangement being such as to prevent lateral'separation.

These ribs, as shown, extend below the next adjacent row of tiles, and raised transverse lelement-s 16 are positioned below lugs (not shown) in the next upper tier of tile engaging in such manner as to prevent separation of the tiles lengthwise. 4 Y

Atene end of the 'tile the ends of the ribs 13 are cut away,- as at 17, and at the other endproject into recesses 18, the walls 19 of which are engageable with corresponding recesses 2O formed in the outer sides of the wall ofthe next adjacent tiles inl their opposite edges. s

These tiles are formed singly in suitable moulds on .pallets7 disposed in the machine, which consist of paired legs 23 connected at theiroends by angle beams 24 and 24 and have bolted on their upper flanged faces crossbars 25.

The pallets, generally designated by the numeral 26, rest on supports 27, in turn resting on adjusting screws 28 threaded into the cross bars `25 and are held in adjustment by check unuts 29.V s

A hollow rectangular box-like frame, comprised of vertical side plates 30 having anged feet 30', are bolted to the cross bars 25, the box having arear end plate 31, shaped in conformity withthetile and a raised front plate 32, thisboxv being receptive of the pallet. The plate 32 has a separable wear member 62 securely attached bv screws 63 acting as dowels and passing through raised eXten- .tions 64 registering with lugs65 formed with the plate 32, thus allowing replacement of the-part most subject to wear.

pair of rails 42 are fastened by their A angedfeet42 to the bars 25, the rails extending longitudinally in parallel with the box sides 30 "from which they are uniformly j ico bar and having collars 40 rotatable in openings formed in the lower sides of the blocks, these collars being held to the reduced cylindrical ends of the screws by screws 41 or other analogous means as preferred.

Thus the distance of the 'bar 33 relative to the rails may be readily adjusted so that its shearing efi'ect on the surfaces 16 may be maintained uniformly, should the rails Wear or for other purposes.

The taiiiping bar, generally designated by the numeral 45, is provided with handles 46, between which is a raised flange 47, the lower side oi the bar being shaped to produce the upper surface of the tile as it is moved over it.

This bar is guided on the rails 42 by spaced lugs 48 and carries a projection 49 adapted to produce the recessl 18 in the tile corner, the recess 2O in the opposite corner of the tile being formed by a projection 50 formed with the front plate 32 of the boX.

Also projecting yfrom the plate `32 are stops' 51 and 51 against which the bar 45 makes contact and by Which the thickness of the tile element 16 is determined.

A pair of curved arms 52 are hingedly engaged to the rear of the structure and carry a shear frame 53 provided with a handle 54, the side walls of this frame being in register with the side Walls 30 of the mould, and acting cooperatively with themV in finishing the sides of the tiles.v

The Wall of the frame adjacent the arms has a block 55 which forms thetile recess 17, and is also provided with a block 56 to form the tile recess 20. s

In operation, the pallet is placed in the mould or box and adjusted to produce the desired thickness of the tile; the bars 33 and 45are removed and the tile material in the smoothing bar 33 placed on the rails, moved to the front, shearing the surplus stock and determining the height of the tile element 16.

The shearing frame is then pressed down over the mould containing the tile, defining its side edges and returned to the position shown.

The tile, together with its pallet, is then foregoing description or shown in the accompaiiying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, is Y 1. A tile making machine comprising a frame, a pair of rails on the sides of said frame, means for forming the loWerside of a tile, a manually operable smoothing bar, blocks dowelled to said bar slidable on said rails, means for adjusting said blocks relative to'said'bar, and guide lugsl on said blocks engaging the sides of said rails. 2. A tile making machine comprising a frame, a'pair of spaced Vrails on said frame, means in said frame for forming a tile, a"

tampiiig bar slidable on said rails, a smoothing vbar removably Vengaging saidV rails,V

blocksdowelled to said bar, and a screw intermediate said Vdo'vvels for adjusting said smoothing bar relative to said rails by raising or Vlowering the same, said blocks having guide members contacting VWith the sides of said rails. Y

This specification signed and witnessed this 28th day of April, 1922.
